BACKGROUND

Field of Disclosure

The present disclosure relates generally to microwave backhauls and specifically management of microwave backhauls.

Related Art

A conventional communications network includes a conventional microwave line-of-sight backhaul to allow for communication of information, such as audio, video, or data to provide some examples, between one or more near end mobile communications devices and one or more far end mobile communications devices. The conventional microwave line-of-sight backhaul represents an interconnected network of microwave relays and/or microwave switches, which allows for communication between the near end mobile communications devices and the far end mobile communications devices using various microwave pathways. The conventional microwave line-of-sight backhaul includes one or more conventional backhaul nodes to route communications between the near end mobile communications devices and the far end mobile communications devices.

The conventional backhaul nodes are conventionally mounted on very large, stable ground-based masts, rooftops, and other existing structures, at vast distances apart at a height that provides a clear view over the surrounding buildings and terrain to faun a macrocell. These vast distances require narrow beams of various antenna elements of the conventional backhaul nodes to be aimed very accurately, within the line-of-sight of one another, to meet network demands, such as quality of service (QoS) to provide an example. Aiming of the various antenna elements of the conventional backhaul nodes is entirely a mechanical process whereby an installer simply adjusts a direction, such azimuth, altitude, pitch, roll, and/or yaw to provide some examples, of the various antenna elements until reaching maximum signal strength. Additionally, the conventional backhaul nodes conventionally operate at high power levels, typically high powered, narrow beams, to allow for their communications to traverse the vast distances between them.

However, environmental factors, such as wind to provide an example, can cause movement, such as jitter or vibration, of the conventional backhaul nodes as well as their associated high power, narrow beams. These environmental factors, as well as other environmental factors, such obstructions from buildings and terrain, for example, tree branches, can cause signal strengths of the conventional backhaul nodes to fluctuate, thereby making aiming of these high powered, narrow beams rather difficult. Additionally, these environmental factors can cause redirection of the high power, narrow beams of the antennas even after being properly aimed. In these situations, the high power levels of the conventional backhaul nodes are further increased to compensate for these environmental factors to maintain the network demands. The redirection of the high power, narrow beams in this manner can cause high powered microwave radiation to be directed directly at populated areas.

Additionally, loss of one or more conventional backhaul nodes can be devastating for the conventional microwave line-of-sight backhaul. For example, one or more conventional backhaul nodes can become inoperative as a result of the environmental factors. As a result, the conventional microwave line-of-sight backhaul can no longer be able to meet the network demands when one or more of the conventional backhaul nodes become inoperative due to the relatively limited number of the conventional backhaul nodes within the conventional microwave line-of-sight backhaul.

Conventional Microwave Line-of-Sight Backhaul Pathway

FIG. 1A illustrates a block diagram of a conventional microwave line-of-sight backhaul. A conventional communications network 100 includes a conventional microwave line-of-sight backhaul 102 to allow for communication of information, such as audio, video, or data to provide some examples, between one or more near end mobile communications devices 104 and one or more far end mobile communications devices 106.

The near end mobile communications devices 104 and the far end mobile communications devices 106 can represent one or more mobile telephony devices, such as one or more mobile phones, one or more mobile computing devices, one or more mobile internet devices, one or more personal digital assistants, one or more handheld game consoles, one or more portable media players, one or more digital still cameras, one or more digital video cameras, one or more pagers, one or more personal navigation devices, one or more tablet computers, and/or any other suitable communications device that is capable of wireless communication within the conventional microwave line-of-sight backhaul 102. As shown in FIG. 1, the near end mobile communications devices 104 and the far end mobile communications devices 106 wirelessly exchange the information using the microwave line-of-sight backhaul 102. Although not shown in FIG. 1, the conventional microwave line-of-sight backhaul 102 can be communicative coupled to various other conventional backhauls, such as a fiber optic backhaul or a cable backhaul to provide some examples.

The conventional microwave line-of-sight backhaul 102 represents an interconnected network of microwave relays and/or microwave switches, which allows for communication between the near end mobile communications devices 104 and the far end mobile communications devices 106 using various microwave pathways 150.1 through 150.k. The conventional microwave line-of-sight backhaul 102 includes one or more conventional backhaul nodes 108.1 through 108.i to route communications between the near end mobile communications devices 104 and the far end mobile communications devices 106. Typically, one or more of the conventional backhaul nodes 108.1 through 108.i, such as the conventional backhaul node 108.1 to provide an example, can include a conventional outdoor unit (ODU) to communicate with a conventional indoor unit (IDU) that is in communications with the near end mobile communications devices 104 and/or the far end mobile communications devices 106. The conventional IDU can additionally function as a communications bridge to pass communications from the near end mobile communications devices 104 and/or the far end mobile communications devices 106 to their respective ODUs.

One of the conventional backhaul nodes 108.1 through 108.i is further illustrated in an exploded view 110. As shown in the exploded view 110, the conventional backhaul nodes 108.1 through 108.i conventionally includes various antenna elements 112 that are mounted onto a fixed, highly stable location 114. The fixed, highly stable location 114 represents any very large, stable ground-based mast, rooftop, and other existing structure. Conventionally, the various antenna elements 112 from one conventional backhaul node 108.1 through 108.i are at vast distances apart from various antenna elements 112 of another conventional backhaul node 108.1 through 108.i at a height that provides a clear view over the surrounding buildings and terrain to form a macrocell. These vast distances require narrow beams of the various antenna elements 112 of the conventional backhaul nodes 108.1 through 108.i to be aimed very accurately, within the line-of-sight of one another, to meet network demands, such as quality of service (QoS) to provide an example. Aiming of the various antenna elements 112 of the conventional backhaul nodes 108.1 through 108.i is entirely a mechanical process whereby an installer simply adjusts a direction, such azimuth, altitude, pitch, roll, and/or yaw to provide some examples, of the various antenna elements until reaching maximum signal strength. Additionally, the conventional backhaul nodes 108.1 through 108.i conventionally operate at high power levels, typically high powered, narrow beams, to allow for their communications to traverse the vast distances between them.

However, environmental factors, such as wind to provide an example, can cause movement, such as jitter or vibration, of the conventional backhaul nodes 108.1 through 108.i as well as their associated high power, narrow beams. These environmental factors, as well as other environmental factors, such obstructions from buildings and terrain, for example, tree branches, can cause signal strengths of the conventional backhaul nodes 108.1 through 108.i to fluctuate, thereby making aiming of these high powered, narrow beams rather difficult. Additionally, these environmental factors can cause redirection of the high power, nano beams of the antennas even after being properly aimed. In these situations, the high power levels of the conventional backhaul nodes 108.1 through 108.i are further increased to compensate for these environmental factors to maintain the network demands. The redirection of the high power, narrow beams in this manner can cause high powered microwave radiation to be directed directly at populated areas. For example, these environmental factors can cause the various antenna elements 112 of the conventional backhaul nodes 108.1 through 108.i to sag over time which requires these various antenna elements 112 to be manually re-aimed on site.

Additionally, loss of one or more conventional backhaul nodes 108.1 through 108.i can be devastating for the conventional microwave line-of-sight backhaul 102. As a result, the conventional microwave line-of-sight backhaul 102 can no longer be able to meet the network demands when one or more of the conventional backhaul nodes 108.1 through 108.i become inoperative due to the relatively limited number of the conventional backhaul nodes 108.1 through 108.i within the conventional microwave line-of-sight backhaul 102. For example, one or more conventional backhaul nodes 108.1 through 108.i can become inoperative as a result of the environmental factors. As another example, failure of certain components, such as the various antenna elements 112 and their associated electronics to provide some examples, of one or more conventional backhaul nodes 108.1 through 108.i cause these conventional backhaul nodes 108.1 through 108.i to become inoperative. In each of these examples, the conventional backhaul nodes 108.1 through 108.i remain inoperative until on site repairs are complete. In some situations, the communications can be re-routed to bypass these inoperative conventional backhaul nodes 108.1 through 108.i by reconfiguring the various microwave pathways 150.1 through 150.k which can slow down of communications within the conventional communications network 100. However, in other situations, the various microwave pathways 150.1 through 150.k must pass through these inoperative conventional backhaul nodes 108.1 through 108.i which can completely stop communications within the conventional communications network 100 until on site repairs are complete.

Advancement in Backhaul Nodes

Recent advancements in microwave backhaul nodes have dramatically altered complexity of conventional microwave backhauls, such as the conventional microwave line-of-sight backhaul 102 to provide an example. A first advancement is the use of a phased array feeder (PAF) for communications among the microwave backhaul nodes as described in U.S. patent application Ser. No. 13/435,604, filed Mar. 30, 2012, which is incorporated by reference herein in its entirety. Unlike various antenna elements of the conventional microwave backhauls, the PAF is configurable to be dynamically aimed. The PAF represents a reconfigurable array of element antennas that is configurable to receive energy in a desired direction and to suppress energy in an undesired direction. The reconfigurable array is configurable to provide various microwave pathways to various microwave backhaul nodes. For example, the reconfigurable array can be configurable to provide a microwave pathway for communications to one microwave backhaul node, commonly referred to as point-to-point.

As another example, the reconfigurable array can be configurable to provide more than one microwave pathway for communications to more than one microwave backhaul node, commonly referred to as point-to-multipoint. In this other example, the reconfigurable array can be physically or logically, in time and/or frequency, separated to provide these microwave pathways. For example, this logical time separation can include one or more configurations, such as from full-duplex PAF to a first microwave backhaul node for approximately fifty percent of the time to a half-duplex PAF to a second microwave backhaul node for approximately twenty-five percent of the time to a half-duplex PAF to a third microwave backhaul node for approximately twenty-five percent of the time.

Second, this configurability of the PAF allows the microwave backhaul nodes to be mounted on flimsy, less stable locations such as light poles, traffic signs, telephone pole, and/or sides of short buildings to provide some examples. This ability to mount the microwave backhaul nodes on less stable structures allows microwave backhaul nodes to be placed at closer distances when compared to the conventional backhaul nodes, to form microcells. As a result of this increased density, the microwave backhaul nodes can operate at lower power levels and/or lower mounting heights when compared to the conventional backhaul nodes.

Additionally, this configurability of the PAF allows the microwave backhaul nodes to operate in environmental conditions while meeting network demands that would otherwise affect the conventional backhaul nodes. For example, when a microwave backhaul node fails or becomes inoperative, a replacement microwave backhaul node can be mounted onto any nearby structure with re-aiming of PAFs of its destination microwave backhaul node being a part of the process. Further, this configurability of the PAF allows various functions of the microwave backhaul node to be controlled centrally, such as allowing for installation, supporting breakdown, or supporting heavy loading for dynamic rerouting through other PAF pathways to provide some examples. This central controlling of the microwave backhaul node allows communications with this microwave backhaul node as well as other microwave backhaul nodes within the microwave backhaul to be dynamically re-routed in real time. This dynamic re-routing of communications within the microwave backhaul can be in response to network demands and/or environmental conditions.

Further, these closer distances between the microwave backhaul nodes permit merger of different radio access technologies, such as Institute of Electrical and Electronics Engineers (IEEE) 802.16 family of wireless-networks standards, commonly referred to as Worldwide Interoperability for Microwave Access (WiMAX), a 3GPP Long Term Evolution (LTE) communications standard, or a Wi-Fi communications standard to provide some examples, into the microwave backhaul nodes and can include bridging and switching related thereto. The central controlling of the microwave backhaul node can also be used to centrally control the bridging and switching of, these different radio access technologies. A failure or malfunction at the microwave backhaul node due to these different radio access technologies can be centrally monitored and/or managed.

Third the IDU has been integrated with the ODU within the microwave backhaul nodes as described in U.S. patent application Ser. No. 13/535,196, filed Jun. 27, 2012, which is incorporated by reference herein in its entirety. The integration of the IDU and the ODU reduces a size of the microwave backhaul nodes when compared to the conventional backhaul nodes. This reduction in the size of the microwave backhaul nodes allows these microwave backhaul nodes to be mounted on the flimsy, less stable locations when compared to the conventional backhaul nodes that are mounted on very large, stable structures.

Backhaul Pathways that use These Advances in Backhaul Nodes

FIG. 1B illustrates a block diagram of a microwave backhaul according to an exemplary embodiment of the present disclosure. A communications network 120 provides allows for communication of information, such as audio, video, or data to provide some examples, between the one or more near end mobile communications devices 104 and the one or more far end mobile communications devices 106. The communications network 120 includes microwave backhaul nodes 122.1 through 122.k for routing of communications between the one or more near end mobile communications devices 104 and the one or more far end mobile communications devices 106.

Each of the microwave backhaul nodes 122.1 through 122.k include a microwave backhaul node 128 mounted onto a flimsy, less stable location such as a light pole 130 to provide an example. The microwave backhaul node 128 includes one or more dynamically configurable PAFs for routing communications among the microwave backhaul nodes 122.1 through 122.k and bridges and switches for supporting communications between mobile communications devices and the microwave backhaul nodes 122.1 through 122.k.

As shown in FIG. 1B, the microwave backhaul nodes 122.1 through 122.k can operate in the environmental conditions. In sonic situations, these environmental conditions can cause a failure or a malfunction of one of the microwave backhaul nodes 122.1 through 122.k, such as the microwave backhaul node 122.k to provide an example. In this situation, a central management module 124 can dynamically reconfigure the communications network 120 to bypass the failed or malfunctioning microwave backhaul node. For example, communications between the microwave backhaul node 122.1 and the microwave backhaul node 122.k can he re-routed to the microwave backhaul node 122.m by the central management module 124.

In other situations, the microwave backhaul node 122.m can represent a newly installed microwave backhaul node within the communications network 120 that is dynamically configured to route communications between the one or more far end mobile communications devices 106 and the microwave backhaul nodes 122.1 through 122.k. The central management module 124 can provide various services to the communications network 120 for assisting an installer in aiming the one or more dynamically configurable PAFs of the microwave backhaul node 122.m toward other dynamically configurable PAFs of other microwave backhaul nodes 122.1 through 122.k. This assistance can include aiming at least a first portion of one of the dynamically configurable PAFs of the microwave backhaul node 122.m toward a second portion of another dynamically configurable PAF of another microwave backhaul node 122.1 through 122.k.

For example, the central management module 124 can gather location information for the microwave backhaul nodes 122.1 through 122.k. This location information can include orientation, compass coordinates such as longitude and/or latitude, azimuth, altitude, pitch, roll, yaw, and/or any other location information of the microwave backhaul node 122.1 through 122.k. The installer of the microwave backhaul node 122.m can retrieve the location information from other microwave backhaul nodes 122.1 through 122.k themselves and/or from the central management module 124 and use this location information to aim the PAFs of the microwave backhaul node 122.m toward these other microwave backhaul nodes.

As another example, the central management module 124 can gather status information for the microwave backhaul nodes 122.1 through 122.k. This status information can include loading of various microwave pathways between the microwave backhaul nodes 122A through 122.k, type of data to be communicated by the various microwave pathways, QoS of the various microwave pathways, power levels for the various microwave pathways, and/or data rates for the various microwave pathways to provide some examples. The installer of the microwave backhaul node 122.m can retrieve the location information from other microwave backhaul nodes 122.1 through 122.k and use this location information to aim the PAFs of the microwave backhaul node 122.m toward these other microwave backhaul nodes. The installer of the microwave backhaul node 122.m can retrieve the status information from other microwave backhaul nodes 122.1 through 122.k themselves and/or from the central management module 124 and use this location information to aim the PAFs of the microwave backhaul node 122.m toward these other microwave backhaul nodes.

FIG. 2 illustrates a block diagram of a microwave backhaul according to an exemplary embodiment of the present disclosure. A communications network 200 includes a microwave backhaul 202 to allow for communication of information, such as audio, video, or data to provide some examples, between the one or more near end mobile communications devices 104 and the one or more far end mobile communications devices 106. The communications network 200 can represent an exemplary embodiment of the communications network 120.

As shown in FIG. 2, the microwave backhaul 202 represents an interconnected network of microwave relays and/or microwave switches which allows for communication between the near end mobile communications devices 104 and the far end mobile communications devices 106. The microwave backhaul 202 includes one or more microwave backhaul nodes 204.1 through 204.m to route communications between the near end mobile communications devices 104 and the far end mobile communications devices 106. The microwave backhaul nodes 204.1 through 204.m represent a dynamically configurable switch fabric that can route communications through various microwave pathways 250.1 through 250.n of the microwave backhaul 202. Communications through the microwave backhaul 202 can traverse from one of the microwave backhaul nodes 204.1 through 204.m to other microwave backhaul nodes 204.1 through 204.m via one of the microwave pathways 250.1 through 250.m, commonly referred to as point-to-point. Each of the microwave backhaul nodes 204.1 through 204.n can represent an exemplary embodiment of one of the microwave backhaul nodes 123.1 through 122.k.

Also, communications through the microwave backhaul 202 can diverge from one of the microwave backhaul nodes 204.1 through 204.m through more than one of the microwave pathways 250.1 through 250.n to other microwave backhaul nodes 204.1 through 204.m, commonly referred to as point-to-multipoint. For example, as shown in FIG. 2, communications from the backhaul node 204.1 diverge to the backhaul node 204.2 via the microwave pathway 250.1 and the backhaul node 204.3 via the microwave pathway 250.2.

Additionally, communications through the microwave backhaul 202 can converge from multiple microwave backhaul nodes 204.1 through 204.m to one of the microwave backhaul nodes 204.1 through 204.m, commonly referred to as multipoint-to-point. As another example, as shown in FIG. 2, communications through the microwave backhaul 202 converge to the backhaul node 204.1 via the microwave pathways 250.(n-1) and 250.n.

The microwave backhaul nodes 204.1 through 204.m can include a communications bridge to pass communications from other communications backhauls, such as a fiber-optic backhaul and/or a cable backhaul to provide some examples. Also, the communications bridge can pass local communications, such as those provided by the near end mobile communications devices 104 and/or the far end mobile communications devices 106 to provide some examples, to the microwave backhaul 202. For example, the near end mobile communications devices 104 and/or the far end mobile communications devices 106 can be operating in accordance WiMAX. In this example, the communications bridge processes these WiMAX communications for routing through the microwave backhaul 202.

As another example, the near end mobile communications devices 104 and/or the far end mobile communications devices 106 within a macrocell, a microcell, a picocell, and/or a femtocell can be operating in accordance the LTE communications standard. In this other example, the communications bridge processes these LTE communications from the near end mobile communications devices 104 and/or the far end mobile communications devices 106 themselves and/or via one or more base stations or access points within the macrocell, the microcell, the picocell, and/or the femtocell for routing through the microwave backhaul 202.

As also shown in FIG. 2, the microwave backhaul 202 can be, optionally, communicatively coupled to other communication network backhauls and/or access infrastructure 206. The other communication network backhauls and/or access infrastructure 206 represents other network backhauls that can include other microwave backhauls, fiber-optic backhauls and/or cable backhauls to provide some examples. For example, the microwave backhaul 202 can represent a backhaul provided by a first service provider while the other communication network backhauls and/or access infrastructure 206 can represent a different backhaul provided by a second service provider. Additionally, the other communication network backhauls and/or access infrastructure 206 can accommodate different communication protocols than that being presently utilized by the microwave backhaul 202.

Direct Management of Backhaul Nodes

The other communication network backhauls and/or access infrastructure 206 can be communicatively coupled to a central monitoring and control infrastructure 208 and/or to a remote monitoring and control infrastructure 210. The central monitoring and control infrastructure 208 represents a server infrastructure, such as a single server or multiple servers, that directly monitors and/or controls the microwave backhaul 202. The central monitoring and control infrastructure 208 can monitor the microwave backhaul nodes 204.1 through 204.m and dynamically configure routing of communications throughout the microwave backhaul nodes 204.1 through 204.m to meet network demands. For example, the central monitoring and control infrastructure 208 can dynamically configure the various microwave pathways 250.1 through 250.n of the microwave backhaul 202 to route communications throughout the microwave backhaul 202.

The remote monitoring and control infrastructure 210 can also directly manage the microwave backhaul nodes 204.1 through 204.m and dynamically configure routing of communications throughout the microwave backhaul nodes 204.1 through 204.m. Management can include assisting with the process of aiming at least a first portion of a first phased array feeder (PAF) of one of the backhaul nodes 204.1 through 204.m toward a second portion of a second PAF of another of the backhaul node 204.1 through 204.m as well as establishing location information and status information for each of the backhaul nodes 204.1 through 204.m. Additionally, the microwave backhaul nodes 204.1 through 204.m can be monitored and/or managed via a local monitoring and control infrastructure 212. The remote monitoring and control infrastructure 210 and/or the local monitoring and control infrastructure 212 can directly manage the microwave backhaul nodes 204.1 through 204.m. Although the central monitoring and control infrastructure 208, the remote monitoring and control infrastructure 210, and the local monitoring and control infrastructure 212 are illustrated as wirelessly communicating with the microwave backhaul 202 and/or the other communication network backhauls and/or access infrastructure 206, those skilled in the relevant art(s) will recognize that the central monitoring and control infrastructure 208, the remote monitoring and control infrastructure 210, and the local monitoring and control infrastructure 212 can also use various wired communications without departing from the spirit and scope of the present disclosure.

Indirect Management of Backhaul Nodes

Alternatively, the remote monitoring and control infrastructure 210 and/or the local monitoring and control infrastructure 212 can indirectly manage the microwave backhaul nodes 204.1 through 204.m by sending requests via the other communication network backhauls and/or access infrastructure 206 and the microwave backhaul 202, respectively, to the central monitoring and control infrastructure 208. In this alternate, the central monitoring and control infrastructure 208 dynamically configures the routing of the communications throughout the microwave backhaul nodes 204.1 through 204.m in response to these requests.

Typically, in this alternate, the remote monitoring and control infrastructure 210 and/or the local monitoring and control infrastructure 212 accesses the central monitoring and control infrastructure 208 using on access point, such as a Wi-Fi access point to provide an example. The remote monitoring and control infrastructure 210 and/or the local monitoring and control infrastructure 212 can then securely, through authentication and/or authorization to provide some examples, access the central monitoring and control infrastructure 208 via a secure connection, such as a secure interface through a web browser to provide an example, through the access point. In this situation, the remote monitoring and control infrastructure 210 and/or the local monitoring and control infrastructure 212 sends requests via the secure connection to the central monitoring and control infrastructure 208 to indirectly manage the microwave backhaul nodes 204.1 through 204.m.

In another alternate, the remote monitoring and control infrastructure 210 and/or the local monitoring and control infrastructure 212 can directly manage some of the microwave backhaul nodes 204.1 through 204.m and indirectly manage other microwave backhaul nodes 204.1 through 204.m by sending requests via the other communication network backhands and/or access infrastructure 206 and the microwave backhaul 202, respectively, to the central monitoring and control infrastructure 208. For example, the local monitoring and control infrastructure 212 can directly manage a first group of one or more of the microwave backhaul nodes 204.1 through 204.m while monitoring and/or managing of a second group of one or more of the microwave backhaul nodes 204.1 through 204.m requires indirect monitoring and/or managing.

Additionally, the remote monitoring and control infrastructure 210 and/or the local monitoring and control infrastructure 212 can directly manage some functionality of the backhaul nodes 204.1 through 204.m and indirectly manage others functionality of the backhaul nodes 204.1 through 204.m by sending requests via the other communication network backhauls and/or access infrastructure 206 and the microwave backhaul 202, respectively, to the central monitoring and control infrastructure 208. For example, the local monitoring and control infrastructure 212 can directly adjust some configurations, such as directionality of their PAFs to provide an example, of the microwave backhaul nodes 204.1 through 204.m while adjustment of other configurations such as QoS to provide an example requires indirect adjustment by sending a request to adjust via the microwave backhaul 202 to the central monitoring and control infrastructure 208.

The first exemplary microwave backhaul node 302 includes a motorized PAF 308, a motorized antenna 310, an all ODU 312, and a split ODU 314 mounted onto a tower 316. The tower 316 can be mounted on very large, stable ground-based masts, rooftops, and other existing structures, at vast distances apart at a height that provides a clear view over the surrounding buildings and terrain. The motorized PAF 308 provides wireless communications between the first exemplary microwave backhaul node 302 and the second exemplary microwave backhaul node 304 and/or the third exemplary microwave backhaul node 306. The motorized PAF 308 can include a PAF or a PAF coupled to an electromechanical device, such as an electric motor to provide an example.

For example, the all ODU 312 can communicate with the motorized PAF 308 while the split ODU 314 and split IDU 318 can communicate with the motorized antenna 310. As another example, the all ODU 312 can communicate with the motorized antenna 310 while the split ODU 314 and split IDU 318 can communicate with the motorized PAF 308.

The all ODU 312 provides functionality typical of a conventional ODU and a conventional IDU as well as a communications bridge to process communications from the access point 324 for routing by the second exemplary microwave backhaul node 304. This functionality of the conventional ODU and the conventional IDU can also be split between the split ODU 314 and the split IDU 318 which can also include a communications bridge. Additionally, the all ODU 312 and/or the split ODU 314 configure or partition the motorized PAF 308 to communicate with the second exemplary microwave backhaul node 304 over a first microwave pathway and to communicate with the third exemplary microwave backhaul node 306 over a second microwave pathway. For example, a first portion of the motorized PAF 308 can be partitioned, in time and/or frequency, to communicate with the second exemplary microwave backhaul node 304 and a second portion of the motorized PAF 308 can be partitioned, in time and/or frequency, to communicate with the third exemplary microwave backhaul node 306.

The second exemplary microwave backhaul node 304 includes a motorized PAF 320, a motorized PAF 322, an access point 324, and an all ODU 326 mounted onto a pole 328. The pole 328 represents a flimsy, less stable location, such as light poles, traffic signs, or telephone poles to provide some examples, when compared to the tower 316. The motorized PAF 320 and the motorized PAF 322 provides wireless communications between the second exemplary microwave backhaul node 304 and the first exemplary microwave backhaul node 302 and the third exemplary microwave backhaul node 306, respectively. The motorized PAF 320 and the motorized PAF 322 operate in a substantially similar manner as the motorized PAF 308.

The access point 324 provides communications between various mobile communications devices, such as the near end mobile communications devices 104 and/or the far end mobile communications devices 106 to provide some examples, within a macrocell, a microcell, a picocell, and/or a femtocell that can operating in accordance with any suitable wireless communication protocols, such as WiMAX, LTE, fourth generation (4G) mobile communications standards, third generation (3G) mobile communications standards, and/or Wi-Fi to provide some examples.

The all ODU 326 provides functionality typical of a conventional ODU and a conventional IDU as well as a communications bridge to process communications from the access point 324 for routing by the second exemplary microwave backhaul node 304. Additionally, the all ODU 326 can include one or more sensors to measure environmental conditions, such as humidity, precipitation, temperature or any other environmental condition, and/or location information, such as orientation, compass coordinates such as longitude and/or latitude, azimuth, altitude, pitch, roll, yaw, and/or any other location information to provide some examples, of the second exemplary microwave backhaul node 304 or a portion thereof such as the pole 328 to provide an example.

The third exemplary microwave backhaul node 306 includes a motorized PAF 330, a motorized PAF 332, and an all ODU 334 mounted onto a mast 336. The mast 328 represents a flimsy structure that is mounted to a stable location, such a side of a short building to provide an example. The motorized PAF 330 and the motorized PAF 332 provides wireless communications between the third exemplary microwave backhaul node 306 and the second exemplary microwave backhaul node 304 and one or more other microwave backhaul nodes. The motorized PAF 320 and the motorized PAF 322 operate in a substantially similar manner as the motorized PAF 308.

Additionally, the all ODD 334 configures or partitions the motorized PAF 330 to communicate with the second exemplary microwave backhaul node 304 over a third microwvave pathway and to communicate with the first exemplary microwave backhaul node 302 over the second microwave pathway.

Management of Exemplary Backhaul Nodes

The first exemplary microwave backhaul node 302, the second exemplary microwave backhaul node 304, and/or the third exemplary microwave backhaul node 306 can be automatically monitored and/or managed and/or monitored and/or managed by a remote monitoring and control infrastructure 338 and/or a local monitoring and control infrastructure 340. The remote monitoring and control infrastructure 338 can represent an exemplary embodiment of the central monitoring and control infrastructure 208 and/or the remote monitoring and control infrastructure 210 and the local monitoring and control infrastructure 340 can represent an exemplary embodiment of the local monitoring and control infrastructure 212.

In some situations, microwave backhaul nodes within a geographical area can be inadequate to meet network demands. For example, power usage between these microwave backhaul nodes can be relatively high and/or throughput between these microwave backhaul nodes can be relatively low. As another example, these microwave backhaul nodes can be inadequate to service a vast number of mobile communications devices that are requesting access. In these situations, additional microwave backhaul nodes can be installed within the geographical area to adequately meet network demands. The description below describes installing the second exemplary microwave backhaul node 304 within a geographical area that is presently serviced by the first exemplary microwave backhaul node 302 and the third exemplary microwave backhaul node 306 to meet network demands. However, this is not limiting, those skilled in the relevant art(s) will recognize that other microwave backhaul nodes can be installed into any geographical area in a substantially similar manner without departing from the spirit and scope of the present disclosure.

Prior to installing the motorized PAF 320, the motorized PAF 322, the access point 324, and the all ODU 326 onto the pole 328 of the second exemplary microwave backhaul node 304, the first exemplary microwave backhaul node 302 coarsely aims the motorized PAF 308 towards the motorized PAF 330 of the third exemplary microwave backhaul node 306. The first exemplary microwave backhaul node 302 can use Global Position System (GPS) information from the third exemplary microwave backhaul node 306 as well as its own GPS information along with the location information and wide beam to narrow beam target processing to coarsely aim the motorized PAF 308. Afterwards, the first exemplary microwave backhaul node 302 communicates with the third exemplary microwave backhaul node 306.

As discussed above, environmental factors, such as wind to provide an example, can cause movement, such as jitter or vibration, of the tower 316 and/or the mast 336. This movement of the tower 316 and/or the mast 336 can be quantified, typically in terms of the environmental conditions and/or the location information by the all ODU 334. The quantification of the movements allows the motorized PAF 308 and/or the motorized PAF 330 to be adjusted using their respective electromechanical devices to substantially compensate for the movement of the tower 316 and/or the mast 336. The first exemplary microwave backhaul node 302 and the third exemplary microwave backhaul node 306 can automatically adjust the motorized PAF 308 and the motorized PAF 330, respectively, or, alternatively, adjust the motorized PAF 308 and the motorized PAF 330 in response to communications from the remote monitoring and control infrastructure 338 and/or the local monitoring and control infrastructure 340.

The first exemplary microwave backhaul node 302 and the third exemplary microwave backhaul node 306 can be characterized as being separated by a long distance apart within the geographical area. This long distance causes the first exemplary microwave backhaul node 302 and the third exemplary microwave backhaul node 306 to communicate with relative high power levels and/or with relatively low throughput. To increase throughput, to allow for another local downstream bridging path, to increase tolerance to the environmental factors, and/or to provide addition redundancy, the second exemplary microwave backhaul node 304 can be installed within the geographical area.

During the installation, the motorized PAF 320, the motorized PAF 322, the access point 324, and the all ODU 326 are mounted onto the pole 328. The motorized PAF 320 and the motorized PAF 322 are simply aimed in approximate directions of the motorized PAF 308 and the motorized PAF 330, respectively. Afterwards, the all ODU 326 can be directed to automatically configure the motorized PAF 320 and the motorized PAF 322 to find, to target, and/or to develop optimal configurations for servicing communications between the motorized PAF 320 and the motorized PAF 308 and between the motorized PAF 322 and the motorized PAF 330, respectively. For example, a low power and/or low data rate communication is provided from the motorized PAF 320 and/or the motorized PAF 322, each of which are providing a wide beam, to the motorized PAF 308 and the motorized PAF 330, respectively. The power and/or data rate of this communication is incrementally increased and/or the beam is incrementally decreased while moving or adjusting the motorized PAF 320 and/or the motorized PAF 322 to target the motorized PAF 308 and the motorized PAF 330, respectively. Alternatively, the finding, the targeting, and/or the developing of the optimal configurations can be performed remotely from the remote monitoring and control infrastructure 338 and/or locally from the local monitoring and control infrastructure 340. In this alternate, the remote monitoring and control infrastructure 338 can be configured to execute hardware, software, or any combination thereof that is tailored for monitoring and controlling the first exemplary microwave backhaul node 302, the second exemplary microwave backhaul node 304, and/or the third exemplary microwave backhaul node 306.

Additionally, the first exemplary microwave backhaul node 302 and the third exemplary microwave backhaul node 306 can be reconfigured to detect communications from the second exemplary microwave backhaul node 304. This reconfiguration can include aiming the motorized PAF 308 and/or the motorized PAF 330 to communicate with the motorized PAF 320 and the motorized PAF 322, respectively. This reconfiguration can also include reconfiguring the all ODU 312, the split ODU 314, and/or the all ODU 334 to recognize communications from the first exemplary microwave backhaul node 304. This reconfiguration can also include dynamically reconfiguring or partitioning the motorized PAF 308 and/or the motorized PAF 330 to communicate with the motorized PAF 320 and the motorized PAF 330 and to communicate with the motorized PAF 308 and the motorized PAF 322, respectively.

After configuration of the second exemplary microwave backhaul node 304, the first exemplary microwave backhaul node 302 and the third exemplary microwave backhaul node 306 can begin to communicate with the second exemplary microwave backhaul node 304. The microwave pathways between the first exemplary microwave backhaul node 302 and the third exemplary microwave backhaul node 306 can be reallocated to include the second exemplary microwave backhaul node 304. For example, communications from the first exemplary microwave backhaul node 302 that are destined for the third exemplary microwave backhaul node 306 can be routed to the second exemplary microwave backhaul node 304 for routing onto the third exemplary microwave backhaul node 306.

As another example, communications from the first exemplary microwave backhaul node 302 and/or the third exemplary microwave backhaul node 306 that are destined for mobile communications devices, such as the one or more near end mobile communications devices 104 and the one or more far end mobile communications devices 106 to provide some examples, that are associated with the access point 324 can be routed to the second exemplary microwave backhaul node 304.

As a further example, some types of data and/or QoS can be routed from the first exemplary microwave backhaul node 302 to the third exemplary microwave backhaul node 306 while other types of data and/or QoS can be routed from the first exemplary microwave backhaul node 302 to the second exemplary microwave backhaul node 304 for routing onto the third exemplary microwave backhaul node 306.

As a yet further example, communications from the first exemplary microwave backhaul node 302 can be routed to the third exemplary microwave backhaul node 306 while communications from the third exemplary microwave backhaul node 306 can be routed to the second exemplary microwave backhaul node 304 for routing onto the first exemplary microwave backhaul node 302.

As an even further example, communications from the first exemplary microwave backhaul node 302 can be routed to the third exemplary microwave backhaul node 306 for a first instance in or first percentage of time while communications from the third exemplary microwave backhaul node 306 can be routed to the second exemplary microwave backhaul node 304 for routing onto the first exemplary microwave backhaul node 302 for a second instance in or second percentage of time.

The allocation of the microwave pathways between the first exemplary microwave backhaul node 302, the second exemplary microwave backhaul node 304, and/or the third exemplary microwave backhaul node 306 can occur automatically or be performed remotely from the remote monitoring and control infrastructure 338 and/or locally from the local monitoring and control infrastructure 340. In some situations, the reallocation of the microwave pathways can be a dynamically adjusted in response to network conditions, such as available bandwidth, loading of various microwave pathways, or type of data to be communicated to provide some examples. For example, communications between the first exemplary microwave backhaul node 302 and the third exemplary microwave backhaul node 306 can be reallocated to the second exemplary microwave backhaul node 304 when the microwave pathway between the first exemplary microwave backhaul node 302 and the third exemplary microwave backhaul node 306 can no longer network demands. This can occur, for example, when the microwave pathway between the first exemplary microwave backhaul node 302 and the third exemplary microwave backhaul node 306 is overloaded.

It is possible that the second exemplary microwave backhaul node 304 can become impaired as a result the environmental factors to provide an example. In this situation, communications from the first exemplary microwave backhaul node 302 to the second exemplary microwave backhaul node 304 that are destined for the third exemplary microwave backhaul node 306 can bypass the second exemplary microwave backhaul node 204 and be routed directly to the third exemplary microwave backhaul node 306. Additionally, it is also possible that one of the motorized PAFs, such as the motorized PAF 322 to provide an example, of the second exemplary microwave backhaul node 304 can become impaired. In this situation, communications from the first exemplary microwave backhaul node 302 that arc destined for this impaired motorized PAF can be routed to the third exemplary microwave backhaul node 306 for routing onto another motorized PAF, such as the motorized PAF 322 to provide an example, of the second exemplary microwave backhaul node 304. This re-routing can occur automatically or be performed remotely from the remote monitoring and control infrastructure 338 and/or locally from the local monitoring and control infrastructure 340.

As another example, the automatic/automated installation service 620 can provide environmental conditions, such as humidity, precipitation, temperature or any other environmental condition, and/or location information, such as GPS) information, orientation, compass coordinates such as longitude and/or latitude, azimuth, altitude, pitch, roll, yaw, and/or any other location information from the control support/application programming interface (API) program service 622 to the installer of the microwave backhaul node 600. Additionally, the automatic/automated installation service 620 can download and/or execute software and/or firmware updates from the central monitoring and control infrastructure, the remote monitoring and control infrastructure and/or the local monitoring and control infrastructure for various modules of the microwave backhaul node 600.

Additionally, the processing module 602 can be configured to execute control support/application programming interface (API) program service 622. The control support/application programming interface (API) program service 622 operates as an interface between the automatic/automated installation service 620 and the elevation, orientation, stability, humidity, temperature, precipitation, imager sensors 606 and/or between the automatic/automated installation service 620 and the access point 618. For example, the control support/application programming interface (API) program service 622 manages the elevation, orientation, stability, humidity, temperature, precipitation, imager sensors 606 to provide the environmental conditions and/or the location information. The control support/application programming interface (API) program service 622 can request the environmental conditions and/or the location information from the elevation, orientation, stability, humidity, temperature, precipitation, imager sensors 606 at periodic intervals and/or can poll the elevation, orientation, stability, humidity, temperature, precipitation, imager sensors 606 for the environmental conditions and/or the location information.

In some situations, the central monitoring and control infrastructure, the remote monitoring and control infrastructure and/or the local monitoring and control infrastructure can remotely provide the environmental conditions and/or the location information via the access point 618. In these situations, the control support/application programming interface (API) program service 622 manages the access point 618 to provide the environmental conditions and/or the location information, such as GPS information to provide an example. The control support/application programming interface (API) program service 622 can request the environmental conditions and/or the location information from the access point 618 at periodic intervals and/or can poll the access point 618 for the environmental conditions and/or the location information.

Further, the processing module 602 can be configured to execute operational program service 624. The operational program service 624 can automatically manage overall configuration and operation of the microwave backhaul node 600. For example, the operational program service 624 manages parameters of the various microwave pathways, such as loading of the various microwave pathways, type of data to be communicated by the various microwave pathways, QoS of the various microwave pathways, power levels for the various microwave pathways, data rates for the various microwave pathways to provide some examples. As another example, the operational program service 624 manages allocation of the various microwave pathways between the microwave backhaul node 600 and other microwave backhaul nodes of a communications network, such as the communications network 200 to provide an example. As a further example, the operational program service 624. Alternatively, the operational program service 624 can provide configuration and operation to the central monitoring and control infrastructure, the remote monitoring and control infrastructure and/or the local monitoring and control infrastructure to be used for configuration and operation of the microwave backhaul node 600.

Yet further, the processing module 602 can be configured to execute local and remote testing service 626. The local and remote testing service 626 includes installation procedures and routines for the installation of the microwave backhaul node 600 as well as testing procedures and routines for testing the microwave backhaul node 600. For example, a low power and/or low data rate communication can be provided by backhaul radios 612.1 through 612.N via their respective PAFs, each of which are providing a wide beam. The local and remote testing service 626 causes an incremental increase in the power and/or data rate of this and/or an incremental decrease in the beam while causing the control for mounting motors 608 to move or adjust the PAFs, to target other microwave backhaul nodes. Typically, the installation procedures and routines and/or the testing procedures and routines are provided by the central monitoring and control infrastructure, the remote monitoring and control infrastructure and/or the local monitoring and control infrastructure.

The user interface 604 provides a user interface for an operator of the microwave backhaul node 600 to interface with the central monitoring and control infrastructure, the microwave backhaul nodes, and/or the microwave backhaul node 600 itself in a substantially similar manner as the user interface 406.

The elevation, orientation, stability, humidity, temperature, precipitation, imager sensors 606 include one or more sensors to provide the environmental conditions and/or the location information. In some situations, the elevation, orientation, stability, humidity, temperature, precipitation, imager sensors 606 can include an imaging device to provide various images of the microwave backhaul node 600. These various images can be used by the viewed by the central monitoring and control infrastructure, the remote monitoring and control infrastructure and/or the local monitoring and control infrastructure to assist in detection of impairments that can be present within the microwave backhaul node 600.

The control for mounting motors 608 can adjust directions such as orientation, azimuth, altitude, pitch, roll, and/or yaw of the PAFs.

The switching controller 610 can configure and arrange various switches of the switch fabric 614 to route communications between the backhaul radios 612.1 through 612.N and/or between the backhaul radios 612.1 through 612.N the access point 618. For example, the switching controller 610 can configure and arrange the switch fabric 614 to route communications received from a first microwave backhaul node via a first backhaul radio 612.1 onto a second backhaul radio 612.2 for transmission onto to a second microwave backhaul node. As another example, the switching controller 610 can configure and arrange the switch fabric 614 to route communications received from a first microwave backhaul node via a first backhaul radio 612.1 onto the access point 618 for transmission onto one or more mobiles communications devices, such as the one or more near end mobile communications devices 104 and the one or more far end mobile communications devices 106 to provide some examples.

The backhaul radios 612.1 through 612.N include various microwave transceivers to communicate with other microwave backhaul nodes via the PAF #1 through PAF #N. The backhaul radios 612.1 through 612.N can be directly configured by the processing module 602 and/or indirectly by the central monitoring and control infrastructure, the remote monitoring and control infrastructure and/or the local monitoring and control infrastructure. This configuration can include activation/deactivation, types and QoS of communication flow to be supported, transmit power level, and/or data rates. The backhaul radios 612.1 through 612.N can additional control partitioning of their PAF #1 through PAF #N to support the various microwave pathways.

The wired interface 616 represents a wired communications pathway between the microwave backhaul node 600 and the central monitoring and control infrastructure, the remote monitoring and control infrastructure and/or the local monitoring and control infrastructure.

The access point 618 provides wireless communications between the microwave backhaul node 600 in a substantially similar manner as the access point 512.
